GAUGE.

`Application filed May 5,

My invention relates to gauges, anda particularly but not exclusively toone for testing and measuring the relation of the walls of a cylinder bore to a given plane, as tor example the end face of the cylinder.

The invention will be best understood from the followingdescription when read' in the light of the accompanying drawing of a specific embodiment of the invention selected for illustrative purposes, while the scope of theinvention will be more particularly pointed out in the appended claims.

In the drawing v Fig. 1 is an elevation of a gauge construct` ed according to the invention; j

F ig. 2 is a plan of the gauge constructed according to Fig. 1, this figure also indicating the application ot' the gauge to a cylin-v der which is to be measured or tested;

Figs. 3 and 4 respectively are sections on `the lines B-B'and 4--4 of Fig. 1, Fig. 3 showing the application of the gauge to a cylinder; and n Fig. 5 is a section on the line 5-5 of Fig. 3. f

Referring to the drawing have shown a base member 1 which herein is provided with a plane bottom tace 3 adapted to rest on the end face 5 of a cylinder block 7 the bore of which block is shown at 8. As shown` the base member has formed integrally therewith an upwardly extending sleeve 9 provided witha bore 11 which receives a transversely extending bar 13 the axis of which normal to the plane of the face 3. Herein the bar 13 is tubular and the outer surface thereor1 is a cylinder, the bar being slidably and rotatably mounted in the Abore 11 so that the bar may be adjusted both lengthwise thereof and rotatably relative to the base member. Suitable means may be provided for securing the base member and bar in their adjusted positions, which means herein is exemplified by a clamp formed by providing the sleeve 9 with a longitudinal split 15 and a cooperating clamping screw 17. j

As shown the tubular member 13 is provided with oppositely disposed, longitudinal slots 19 in which are slidably mounted the respective opposite end portions ot a block Q1 held against transverse displacement relative to the bar 13 by a sleeve 23 slidably fitting the exterior of the bar and connected 1927.` Serial No. 189,133.

to the block byjscrewsQl. Herein secured adjustable relative to the casing for setting p its zero mark under the pointer.` j As shown `the sleeve 33 of the indicating device `is removably inserted in the bore of a tubular bushing 37 carried at the upper end of the rod 25, the bushing and rod being split at their upper ends as indicated at 41 to render the end portions thereof resilientk and adapting them to be clamped against `the sleeve 33 by use of a split clamping band 43 having the operating screw 45. It will be observed by this construction that the casing of ythe thousandths of an inch and being 'rotatably i indicating device isremovably attached to y the rod `.55, and may be turned in diiferent positions relative to the bar.

As shown the block 21, which slidingly fits the sides of the groove 19 of the tubular bar 13 so as to prevent rotation of the block relative to the tubular member, carries a .belt

crank lever 47 pivoted to the block at 49, i

the bloclrand sleeve 23 being slotted as indicated respectively at 50 and 51 for receiving this lever. One leg 53 of the bell crank lever projects through the slot and sleeve and,

constitutes a contact eeler adapted to contactwith the wall of the cylinder.bore,while `the opposite leg 54 contacts with a rod 55 slidably mounted at 57 and 59 respectively in the block 21 and bushing 87. the upper` end of the rod 55 contacting with the act-uating rod 35 of the :indicating device so that movement of the bell crank `lever will actuate the pointer of the `indicating device. Convenientlythe bore 11 oi the base mem-` ber may be counterbored adjacent its lower end to provide a recess 61 for receiving the ring Q3 when at the upper limit of its travel `relative to the bar 13. which construction permits the Contact feelerto operate upon LLe? ` that ortien ef Lfhe `Wallethe cylinder bore gh'ereiill describe' l, l
